Sharing your snack: unusual observation of a chick–chick feeding occurrence in colonial king penguin (Aptenodytes patagonicus)
Abstract King penguins ( Aptenodytes patagonicus ) are colonial seabirds presenting an extraordinary breeding cycle. Parents take over 14 months to raise a single chick to independence, upon which fledglings depart at sea for more than a year. Juveniles often return to the colony within the three au...

Abstract King penguins ( Aptenodytes patagonicus ) are colonial seabirds presenting an extraordinary breeding cycle.
